TRANSOM AND WINDOW OPERATING MECHANISM.

T 0 all whom it may concern:

Be it known that I, FRANK A. BLIOKLEY, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inTransom and Window Operating Mechanism, of which the following is aspecification.

My invention relates to improvements in transom and window operatingmechanism, the object of the invention being to provide improved meanswhereby the transom or window can be opened and held in open position,but which when released will be antomatically closed.

A further object is to provide improvements of this character, which canwith but slight alteration be used on transoms hinged at the middle, orat the bottom, or on casement windows or other similar devices.

With these and other objects in view, the invention consists in certainnovel features of construction, and combinations, and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaims.

In the accompanying drawings, Figure 1, is a view in elevationillustrating the application of my improvements to a transom, such asordinarily used having horizontal pivot pins at its center. Fig. 2, is aside view of Fig. 1. Fig. 3, is a view in section illustrating the rodclamping device, and Figs. 4 and 5, are views illustrating theapplication of my improvements to a window hinged at the side.

As shown in Figs. 1, 2 and 8, 1 represents an ordinary transom, and 2 aframe. 3 represents a link which is provided near its upper end with aslot 4, into which a cross pin 5 in a bifurcated bracket 6 is disposed.The link 3 is located in the bifurcated bracket 6, and the latter issecured to the transom above the pivotal point of the latter. The lowerend of this link is connected by a pivot pin 7 with a link 8, and thelatter has an angular sleeve 9 at its lower end, mounted upon theangular end of a shaft 10, which latter is mounted to turn in a casing11 secured to the frame 2, and has a coiled spring 10 thereon to eXertrotary pressure on the shaft and link 8 for a purpose which will morefully hereinafter appear. The pivot pin 7 also pivotally connects a link12, which latter at its upper end is provided with a cross pin 13,mounted to move in a slot 14 on the guide bracket 15,

the latter secured to the frame 2. This pivot pin 13 also pivotallyconnects the vertical rod 16 with the link 12, and the rod 16 eX- tendsdownwardly in convenient reach of the person on the floor, and passesthrough a casing 17 secured to the frame. The casing 17 is provided witha vertical bore to ac cominodate rod 16, and has a spring dog 18 adaptedto enter any of a series of notches 19 in the rod 16, and hold the rodagainst vertical movement. A button 20 is provided on the casing, and isadapted when forced inward to release the dog from locked engagementwith the rod, and hence permit the latter to move upwardly. 21 indicatesa spring latch on the transom to lock the same, and the locking bolt 22of this spring latch is connected by a cord or other flexible connectingdevice 23 with a pin 34 on the link 3, so that when the latter movesdownwardly, its first movement will serve to unlock the latch.

The operation is as follows: I/Vith the parts as shown in. Figs. 1, 2and 3, when rod 16 is drawn downwardly, the pin 13 will be moveddownwardly, thus forcing downwardly and outwardly the pivotal pin 7,drawing the link 3 downwardly, until the upper end of the slot 4 reachespin 5, the latch 22 being unlocked, the link 3 will engage the bracket 6and draw the transom to open position. As the transom is drawn to openposition, the downwardly and outwardly pivotal movement of the pin 7will swing the link 8 and turn shaft 10 against the action of the spring10*, and the rod 16 can be locked by means of the dog 18 in casing 17 tohold the transom in open posi tion. When this dog is released however,by means of its button 20, the spring 10 will force the parts to move indirections opposite to those above described to close the transom.

As shown in Figs. 4 and 5, to adapt my improvements for a window hingedat the side, but slight modification is necessary. In this construction,I dispense all together with the guide 15, and connect the link 12directly with the rod 16, the latter being preferably shorter than shownin the preferred form. I also employ an additional link 24, whichconnects the pivot pin 7 with a pivot pin 25 in a countersunk socket 26in the window casing 27, and operate the rod 16 by a chain or otherflexible connecting device 28 passed over a pulley 29 on the frame 27and secured at various adjustments by means of a hook 30 on the casing.The link 8 is provided with an 0 ening 31 near its end, and alongitudinaF slot 32. The opening 31 is employed, when the parts areused as shown in Figs. 1, 2 and 3, to receive the pin 7, but when usedas shown in Figs. 4 and 5, the pin is passed through the slot 32. Thisallows a certain longitudinal movement of the pin 7 within the slot tocompensate for the swinging movement of link 24.

In windows of the kind shown in Figs. 4 and 5, the window latch 33 issome distance from the up er edge of the window, and to operate thislatch, I have provided the link 3 with a depending rod or pin 34, whichis connected by a chain 35 with the latch. In this modification I employthe same construction of casin 11, spring 10 and shaft 10, as shown inthe preferred form, in fact, the parts are perfectly interchangeable,and for this reason I have used the same reference characters in thepreferred form and in the modification of such parts as areinterchangeable. In other words, the link 3 which is in both formsconnected to bracket 6 on the window or transom, is pivotally connectedin both instances to links 12 and 8, and the latter to the springpressed shaft.

A great many slight changes might be made in the general form andarrangement of parts described without departing from my invention, andhence I do not restrict myself to the precise details set forth, butconsider myself at liberty to make such changes and alterations asfairly fall within the spirit and scope of my invention.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. In a device of the character described, the combination with a hingedwindow and easing, of a spring pressed shaft on the easing, a lug on thewindow, a link fixed to turn the said shaft, a link pivotally connected.to said lug and said first mentioned link, a third link pivotallyconnected at one end to the pivotal connection of said first mentionedinks, and means for moving said last mentioned link so as to move theivotal connection between said links an turn said shaft.

2. In a device of the character described, the combination with a hingedwindow and a frame, of a casing secured to the window frame, a springpressed shaft in said casing, a link fixed to turn the said shaft, asecond link pivotally connected to the first mentioned link and having alimited sliding engagement with the window, a spring latch for thewindow, a flexible connecting device between said spring latch and thelast mentioned link, and a third link pivotally connected. at thepivotal connection of the first mentioned links, and means for movingsaid last mentioned link so as to swing the first mentioned link andturn the shaft.

3. In combination with a hinged window and a casing, of a spring pressedshaft on the casing, a lug on the window, a link fixed to turn the saidshaft, a second link having limited sliding engagement with said lug andpivotally connected to said first mentioned link, a latch on the window,a flexible connecting device between said latch and the end of said lastmentioned link, a guide bracket on the casing having a longitudinalslot, a link pivotally connected at one end to the pivotal connection ofsaid first mentioned links, a pin at the other end of said lastmentioned link movable in said slot in the guide, a rod pivotallyconnected to said last mentioned lmk, and means for locking said. rodagainst movement.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
